Description

frame positioning structure

technical field

The invention relates to a positioning and clamping structure and a structure for adjusting a terminal positioner by using an adjusting pad as a compensation link.

Background technique

In the process of industrial production and processing, some workpieces with special shapes and structures are often difficult to be clamped and positioned, such as the irregular shape of the lower wall panel frame, and there are multiple ribs (or tendons) on the clamped surface. artifact. When clamping and positioning this kind of workpiece, there are often the following problems: first, when the workpiece is close to the clamping and positioning device, the ribs and other protruding parts on it are easy to interfere with the position of the clamping and positioning device, and the two need to go through a process. Contact can only be achieved through a relatively complex movement process; secondly, due to the influence of factors such as machining accuracy and different clamped surfaces, there may be certain differences in the position of the workpiece after clamping and positioning in three-dimensional space, and targeted adjustments are required. Only after fine-tuning can it meet the requirements, but this kind of adjustment is relatively cumbersome in the past.

Compared with the prior art, the present invention has the following advantages:

This type of frame positioning structure has simple structure, ingenious design and reasonable layout. It aims at the various problems existing in the traditional clamping and positioning structure when clamping and positioning some special-shaped workpieces. Design a structure that can adjust the specific position of the workpiece support surface in space according to the needs. This structure is characterized by convenient adjustment, maintenance and stability, which is better than the mortar adjustment method.

At the same time, the positioning clamp mechanism solves the problem that the protruding parts of the workpiece (such as ribs, ribs, etc.) interfere with the general positioning structure, and a special positioning clamping structure is designed. This positioning clamping structure can be used during the workpiece installation process. Make room for the interference between the supporting positioning surface and the workpiece. After the workpiece is installed, the positioning clamp is clamped to provide the positioning surface.

Because the manufacturing process of these two inventions is simple, the manufacturing cost is low, and they have a wide range of application, they are particularly suitable for popularization and application in this field, and their market prospects are very broad.

detailed description

The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. As shown in Figures 1 to 4: a frame positioning structure, including a first pillar 1 as a foundation, a second pillar 2 is connected to the top of the first pillar 1, and the other end of the second pillar 2 is a longitudinal installation surface 3. A transverse support 4 is fixedly connected to the longitudinal mounting surface 3, and a longitudinal support 5 is fixedly connected to the transverse support 4. The top end of the longitudinal support 5 is a workpiece supporting surface 6; clamps 9 on the first pillar 1, At the end of the clamp arm 10 of the positioning clamp 9, a clamp adjustment block 11 is provided. This clamp adjustment block 11 can directly contact the clamping surface of the workpiece to be clamped, and an adjustment pad is also provided to match the clamp arm 10. 12 is also provided with a horizontal support 7, and the end of this horizontal support 7 is symmetrically provided with a clamping clamp 8, a positioning clip and a positioning block 13. When the clamp arm 10 moves to contact with the positioning block 13, the positioning block 13 will The stop movement of the lower pliers arm 10, that is, the adjustment block 12 and the positioning block 13 play the role of limiting the movement limit position of the pliers arm 10, and a Z-axis adjustment pad 14 is arranged between the first pillar 1 and the second pillar 2. A Y-axis adjustment pad 15 is arranged between the connection surface of the longitudinal mounting surface 3 and the transverse support 4, and an X-axis adjustment pad 16 is arranged between the connection surface of the transverse support 4 and the longitudinal support 5, and the specific thickness of the adjustment pad can be selected. Or adjust the number of pads to change the three-dimensional position of the contact surface between the positioning structure and the workpiece.

The working process of the positioning structure of the frame of the lower wall plate in the embodiment of the present invention is as follows: first, according to the actual situation and needs, the adjustment pads of different thicknesses (or the adjustment pads of different numbers but the same thickness) are selected to realize the final support or clamping of the workpiece. After the position of the station in three-dimensional space is adjusted, the workpiece is placed on the device by hoisting equipment. Before the workpiece approaches the device, the clamping clamp 8 and the positioning clamp 9 need to be opened respectively. After opening, the protruding parts (such as ribs, ribs, etc.) on the workpiece will not be in contact with them during movement. After the protruding parts have moved, control the clamping clamp 8 and the positioning clamp 9 to clamp the workpiece together. During the clamping process, the clamp adjustment block 11 on the positioning clamp 9 directly contacts the clamped surface of the workpiece, and the final position of the clamp adjustment block 9 is determined by the adjustment block 12 and the positioning block 13, that is, the workpiece is determined. The position of the clamped surface, and the end of the clamping clamp 8 is matched with the clamp adjustment block 9, and the two clamp and position the workpiece; use the adjustment block 12 and the positioning block 13 to fix the position of the clamp arm 10, In order to ensure that the clamp arm 10 is in the same position each time it is clamped, a workpiece positioning datum surface that can be adjusted according to actual needs is provided by adjusting the thickness of the clamp adjustment block 11 .

After the workpiece processing is completed, reopen the clamping tongs 8 and the positioning tongs 9, and utilize the lifting device to take the workpiece away from the device.

Use the Z-axis adjustment pad 14 between the first pillar 1 and the second pillar 2 to adjust the position of the workpiece support surface 6 on the Z-axis, and use the Y-axis adjustment pad 15 between the connecting surface of the longitudinal mounting surface 3 and the transverse support 4 Adjust the position of the workpiece support surface 6 on the Y axis, and use the X-axis adjustment pad 16 between the connecting surface of the transverse support 4 and the longitudinal support 5 to adjust the position of the workpiece support surface 6 on the X axis. Measure the spatial coordinates of the X, Y, and Z axes, and calculate the difference between the theoretical coordinates and them, and adjust the thickness of each adjustment pad according to the difference, so as to meet the accuracy requirements of the 6 spatial coordinates of the workpiece support surface.
